Sport stars train hard, have strong self-belief and have a competitive edge that drives them to be the best. 

Athletes at any age, at any level across the world play sport because they all have a burning desire to win. 

If you don't have the passion to win, then what's the point?

There is a formula that make elite athletes tick. 

Having the talent to reach the highest level you can in any sport is important, having the confidence to walk the walk is something else. 

Athletes like Roger Federer and Gary Ablett are champions of their sport. 

They, like many others, have managed to deal with their successes with great humility. 

They are arguably the best players of their sport in the past 10 years and have handled their wins and more importantly their losses with grace and dignity. 

There has been a lot of talk about how Nick Kyrgios (pictured) and how the rising tennis star has handled himself throughout the Australian Open. 

The amount of pressure that has been put on his shoulders over the past week has been extraordinary, but like with any Australian sporting heroes, the more you perform on the big stage the greater the microscope. 

He is a dangerous player who isn't afraid to lay out his emotions out on court.

One minute he could be cursing, the next fist-pumping the air.  

He has no fear, doesn't care what people think of him and loves the attention he is continuing to get.  

The haircut, the earring and the amount of swagger he already has can be disheartening, but for now Kyrgios has been able to back it up with the results. 

Some may call his explosive reactions and often bizarre court-side interviews as arrogant, while others would say the unpredictable nature of his game is all part of the Kyrgios charm. 

But who knows, he might mature as he gets older and that fearless showmanship might fade, I certainly hope not.  

Bernard Tomic is another who has had a tumultuous start to his career. 

More people hated him than loved him, but over the course of the past week he has shown a more professional side to his personality and has won some fans because of it. 

Cricket star Dave Warner is another who often can blur the line between being cocky and confident.

He isn't afraid of pushing the boundaries, but pardon the pun, the batsman has the runs on the board to back it up. 

The on-field flair and audacity we see from some athletes may masquerade as arrogance, when really all they are aiming to do is play their own game.

Regardless if you love these sports stars or not, there is no doubt it provides fans with great entertainment.
